Design of Water Distribution Network for Malliala Village, Telangana using EPANET

Abstract

Water is one of the most essential natural resources supporting life on Earth, and both its availability and quality play a critical role in shaping human well-being and livelihoods. Although freshwater exists in abundance globally, it is often unevenly distributed in space and time, and its quality may not always be suitable for domestic use. In this context, the present study focuses on developing an efficient water distribution network for Malliala Village using the EPANET platform to reliably meet domestic water requirements. As population growth directly influences future water demand, population projection techniques were applied to estimate the design-period population and corresponding water needs. Spatial information required for network planning was generated using Google Earth Pro and ArcGIS, enabling accurate assessment of village layout, settlement patterns, and service coverage. The design approach incorporated the number of households, projected population, estimated demand, and discharge from the overhead tank. The network consists of concrete and HDPE pipes, assigned roughness coefficients of 140 and 145 respectively, and was formulated for continuous 24-hour operation. Hydraulic analysis was carried out using EPANET 2.0 to determine node-specific parameters such as actual demand, pressure, and hydraulic head, along with pipe characteristics including flow, velocity, and unit head loss. The results confirm that the designed system is capable of delivering adequate water throughout the network under the assumed operating conditions.
